SEISMIC REFRACTION SURVEY
Application
- Utilized to predict depth of bedrock, determination of rock strength/rippability, layer thickness, soil stability, landfill investigations
Seismic velocity model
SEISMIC REFLECTION SURVEY
-Used for mapping layer thickness, bedrock level, topography, horizontal profiling void and sinkholes, mapping of faults and horizontal fracture zones and where high detail is necessary or is an or complex geological environment
MASW (Multichannel Analysis of Surface Waves)
Evaluation of ground stiffness by measuring shear-wave velocities
CROSSHOLE SEISMIC
Determines physical properties of the soil from the seismic velocities measured
CROSSHOLE ANALYZER
Determines the structural integrity of drilled shafts and other concrete piles
Reliable method for assessing the integrity of deep foundation elements such as newly placed concrete drilled shafts and slurry walls
Seismic Refraction

Crosshole Analyzer
High Resolution Acoustic Televiewer (HRAT)
The High Resolution Acoustic Televiewer (HRAT)® provides a continuous high-resolution oriented ultrasound image of the borehole wall.
Gyro Inclinometer
The Gyro probe acquires borehole inclination/azimuth logs in situations where metal casing or magnetic materials around the borehole prevent use of the standard verticality probe.
PS Logger
The PS Logger probe measures P (compression) and S (shear) wave velocities in a single borehole without the need for external energy sources
